Android 發送本地廣播 以及創建廣播接收器

1、創建本地廣播接收器

public class MainActivity extends AppCompatActivity{
    private Button mBtn;21     private BindService.MyBinder mMyBinder;
    private MyReceiver mMyReceiver;                       //創建廣播接收器類變量
    private LocalBroadcastManager mLocalBroadcastManager; //創建本地廣播管理器類變量

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mMyReceiver = new MyReceiver();                                                     //實例化廣播接收器 MyReceiver()
        IntentFilter filter = new IntentFilter("com.package.yanglei.action.test");          //動態配置廣播接收器action
        mLocalBroadcastManager = LocalBroadcastManager.getInstance(this);                   //廣播變量管理器獲得本地廣播管理器
        mLocalBroadcastManager.registerReceiver(mMyReceiver, filter);                       //注冊本地廣播


        mBtn = findViewById(R.id.mOnclick);
        mBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                Intent intent = new Intent("com.package.yanglei.action.test");      //創建發送廣播的Action
                intent.putExtra(Intent.EXTRA_TEXT, "hi lllllllllll");                //發送攜帶的數據
                mLocalBroadcastManager.sendBroadcast(intent);                               //發送本地廣播
            }
        });

    }

　　//廣播接收器
    private class MyReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.i("hhhhhhh0", intent.getStringExtra(Intent.EXTRA_TEXT));　　//獲取文本
        }
    }
}
